Removing Empty Disk from Array [Solved]


Recommended Posts

So, I had a precleared disk laying about and decided to add it to a open slot in my array. No problem there, it formatted and I was off to the races. However, just after (of course), I noticed one of my older disks is showing signs of age. Is there an easy (safe) way to remove that newly added, empty disk and just rebuild the dodgy disk onto it without having to rebuild parity. Nothing has been written to the array since adding the new disk.

Thanks. Just one stupid question, where the clear and remove option says "Make sure that the drive you are removing has been removed from any inclusions or exclusions for all shares, including in the global share settings." Does this apply to settings that are set to "all", as well. SO basically just change all the inclusions and exclusions to "none".

This is not quite true as you said you had formatted it.    Formatting is a write operation that creates file system control structures on the disk (and updates parity to reflect this).   Attempting to simply remove the disk at this stage therefore invalidates parity.    If you had left the disk in its pre-cleared state (I.e. all zeroes) without formatting it then it could have been removed without invalidating parity.
